The Smithsonian and the U.S. Postal Service recently signed a lease agreement for the additional space to build the William H. Gross Stamp Gallery. This new space will be added to the museum’s existing 65,000 square feet and is scheduled to open in the next couple of years.

“Don has been a great supporter of the programs that will build the future of stamp collecting and the creation of the next generation of philatelists,” said Allen Kane, director of the museum. “His participation in the Stamp Gallery is another example of how his support will allow millions of people to see the beauty of stamps and better understand the history, heritage and identity of the United States.”

“Stamps enhance our understanding of history and of what it means to be an American,” said Sundman. “The stamp gallery is a chance to introduce new collectors to collecting in an unbelievable space. It is a chance to make a difference.”

Sundman is actively involved with the American Philatelic Society, serves as the chair of the museum’s Council of Philatelists and supports the museum’s Maynard Sundman Philatelic Lecture series.

The National Postal Museum is devoted to presenting the colorful and engaging history of the nation’s mail service and showcasing the largest and most comprehensive collection of stamps and philatelic material in the world. It is located at 2 Massachusetts Ave. N.E., in the Old City Post Office Building across from Union Station. The museum is open daily from 10 a.m. to 5:30 p.m. For more information visit the museum’s Web site at postalmuseum.si.edu.
